in Door-Holders, oi' which the following ie' a specification.

My invention relates to door 'checkin or heldere whose function it is, when attached to the door, to hold the saine onen er 'partly open and prevent its slamming or closing.

The invention further relates to such a device which, aiitoinatically end without edn justment by the hand or icot has the four functions: to olier no resistance to the opening of the door; to oli'er a temporary resistance to the closing' of the door from any open er partly open position, euch resistance i eiing sullieient to prevent occidental closing of the door; to yield to a snilieientiy strong); push or vpull on the door when il. 'is desired. to close it; :ind lo assume an inoperative position alter it so yields, so thnt it then ready to perform its first mentionedfund tion of non-resistance,

The invention has for its object to construct and provide z door holder or check which will have the above'described inode oit' operation and useful liunctione5 and it consists inthe parts and con'ibinations tliereoit hereinafter described and pointed out in the claims.

In order to make my invention .more clearly understood l have shown in the accon'ipanying drawings ineens for carrying the .saine into practical eil'cct, without limit ing my improvements, in their useful applications, to the particular constructions which, for the purpose et explanation, ll have illustrated.

In Said drawing` z- Figure l. is a side elevation el a door holder or check enibodying; my invention, and an edge view oli a portion of e door to which the saine is attached., the holder being in the position it takes when the door is closed.

.ilgilrn has been opened. for four or .tive inches orto a greater distance or entirely.

liig. e is a sectional view on line Fil-EV off iig. 5 ie a. horinental section on line iL-lf Referring to the drawings, Il is a. t ertion of an ordinary .swinging door to en holder is LShown as applied, the bottoni ol" the door being indicated et 3 llexihle spring anni which can he of varieersliaiies not inconsistent with the useful one eration of the device, the preferred shape being' about suini-circular, with an in' gra-. extension el which is or may be rigidly' at tached to the door, by screws 5 or other suit ahle ineens. At its tree end, which its adapted to have :in up .and down spring yielding motion, the arm carries a pivot ii. This is preferably accomplished by forming the end oi? the spring with. an eye or bearing i into which the pivot is ineerted.

l0 is a .ciwingahle leg; comprising an upper member ll and a. lower :member l2 connot hear tightly en the links but allow the tree moveinrnit et the leg elementson both of said pivots. 'lne lower leg,` element is extended above the pivot 13 between Said links, indicated at 16, and is fortified with.

lateral shoulders 17 which may bear against 105 the edge oi the upper leg; element, on the side oi? the same toward the door (Fig. 3). This engagement takes place when the axis of the iivot '13 is a little te the outer side of a straight line which would connect the exis of the pivot 6 with the point at which the lower extremity of the device bears upon the Hoor. The parts l1 and 12 thus have a toggle action, the toggle being locked when vthe shoulders 17 bear against. the upper leg element.

The lower end of the part 12 is screw threaded as indicated at 18 to receive the nut 19 and a soft rubber foot 20. This conapplied was l, position shown in the leg being struction enables the said foot to be screwed up or down to regulate the operative length of the leg, and the foot is held in adjusted position and from working up by the nut 19.

@ther forms of foot and .adjusting means, are within the scope ol my invention.

Such being the preferred construction of the device its operation is as follows:

-When the door to which the holder is last closed the parts were left substantially inthe position shown in Fig. 1. if the door is now opened the leg element 11 will be carried over by the pivot 6 to the position indicated in Fig. 2, and awayfrom the shoulders 17. This movement will tip the lower element 12 into substantially upright position, and a further opening of the door will cause the leg to trail after the pivot 6in substantially the position shown in full lines in Fig. 3. lt will be seen that in the above described opening movement of the door the leg oers no resistance, and the door may be opened .is far as desired, orentirely. But the door cannot now be accidentally closed, because the toggle has become locked (Fig. 3) and presents a stid leg between the pivot 6 and the floor. In this position the holder oilers a temporary,V and eilicient, resistance to any closing movement of the door. Cif the door be intentionally pulled or pushed, ordinarily b the knob, the foot 20 will not slide on the oor but will engage the saine and the pivot 6 will be moved over to a position substantially perpendicular above the foot,

turned over to the position shown in dotted lines in Fig. 3, thereby pushing up the pivot 6 and exing the spring 3, they resistance of which spring has to be overcome in this operation. last mentioned position the spring offers no further resistance to the closing of the door, and even .assists the same, until the spring returns to normal position, and in such further closing of the door the leg tips over tosubstantially 'the position shown in Fig. 6 and thereafter trails after the pivot ,6 until the door is closed, thus automatically assuming the inoperative and non-1'esistant Fig. 1.

in applying the holder to a door the foot 2O is located on the lower leg element so that it may be screwed further upward, and the spring extension l is attached to the door at such height as will give the proper inclination to the leg when the latter From this Leerstoel is in the position shown in Fig. 3, so that the foot will not slide on the floor but will take hold of the same and cause the leg to turn. If, on trying the operation of the holder, its temporary resistance is found to be too strong the nut 19 and foot 20 are screwed farther upward on thc log until such resistance is suilicient for the purpose but not too much.

21l is a rubber buffer attached to the outer end of the spring 3, the spring acting mainly as the buffer and the rubber 21 preventing any marring of the wall against which the door may be swung.

l lt is seen from the above that the improved door holder is provided with means whereby the spring is flexed temporarily during the first part of the closing movement of the door, as the pivot 6 passes the vertical plane of the leg, and whereby the leg automatically assumes an inoperative trailing position in either direction, with the spring normal, except during said time when the spring is flexed.

The holder having the described modeof operation is particularly useful on uneven floors. To illustrate, it often happens that the floor is higher near the door sill than it is farther back where itis desired that the device shall hold thc door open. If the holder resisted in both directions it would have an objectionably strong resistance to opening the door in order that it might have a suilicient resistance at the holding point. It is readily seen that my improved holder obviates such difliculties.

VVhat'I claim is:

1. A door holder comprising a swingable leg having a floor-engaging foot, and a pivot for said leg, said holder having a flexible spring, and means comprising two pivotally connected members which `i'orm said leg whereby the spring isflexed temporarily during the first part of the closing movement of the door and whereby the leg automatically assumes an inoperative trailing position in either direction except during said time when the spring is flexed.

2. A. door holder comprising a swingable leg having a floor-engaging foot, and a pivot for said leg, said holder having a flexible spring, and means comprising two pivotally connected members which form said leg whereby the spring is flexed temporarily as the leg assumes a Vvertical position durin the first part of the closing movement. of the door and wherebythe leg automatically assumes a vertical position without flexure of: the spring during the opening movement of the door and an inoperative trailing position in either direction except during said time when the spring is flexed.

3. A door holder comprising a swingable leg having a {loer-engaging foot, and a pivotk for said leg, said holder. having a :flexible Leaded@ spring, and means comprising two pivotally connected members which form said leg )whereby said leg causes the iiexure of the :spring as the pivot passes the vertical plane `oit the leg on the closing movement of the door and leaves the spring normal as the pivot passes said plane on the opening move? ment of the door.

4. A. door holder comprising a swingahievv [of the leg on the closing movement of the,

door and leaves said spring normal as the pivot passes said vertical plane on the opening movement of the door.
